Vaporeon

The cheapest copy at £2.97 is flagged as played, so a clean one should command more—that's the catch with the broad range here. This card's had real momentum, up 15.4% this week and 40.8% this month, though it's still within its 30-day band of £3.04 to £4.28. Most UK stock is played (76% of known listings), which makes a Near Mint copy genuinely scarce, and the median ask sits at £5.45—nearly double the rock-bottom price. If you're after the foil, expect to pay 2.7× more at around £11.57.
